is complete.
Align the print cartridges
Whenever you install a new print cartridge, you  should align the print cartridges for the
best possible print quality. If your printout is  grainy, has stray dots, jagged edges, or
the ink is bleeding into another color, you  can realign them through the Toolbox or
printer driver (Windows), the HP Printer Utility (Mac OS), or the Toolbox software for
PDAs (Pocket PC and Palm OS). For information about using these tools, see 
Use
device management tools .
NOTE: Load plain paper into the paper tray before aligning the print cartridges.
An alignment page is printed during the alignment process.
• Toolbox (Windows):  Open the Toolbox. For more information, see Toolbox
(Windows). Click the Printer Services  tab, and then click  Align Print Cartridges
and follow the onscreen instructions.
• HP Printer Utility (Mac OS):  Open the HP Printer Utility. For more information,

							Print with a single print cartridge
If one of the print cartridges runs out of ink before you can replace it, you can still print
with a single print cartridge.

cartridgeColor and grayscale
NOTE: Printing with one print cartridge might be slower and the print quality might
be affected. It is recommended to print  with both print cartridges. For borderless
printing, the tri-color print cartridge must be installed.
Calibrate color
If you are not satisfied with the appearance of colors, you can calibrate the colors
manually to ensure the best print quality.
NOTE: Calibrate the color only when the tri-color and photo print cartridges are
installed together. The photo print cartridge is available for purchase as an optional
accessory. For more information, see 
HP supplies and accessories .
NOTE:If you are using a Pocket PC or Palm OS device, you can calibrate the
color using the Toolbox software for PDAs. For more information, see 
Toolbox
software for PDAs (Pocket PC and Palm OS) .
Color calibration balances color tints on printed pages. It is only necessary if:
• Printed colors have visibly shifted toward yellow, cyan or magenta.
• There is a color tinge in the gray shades.
Low ink levels in the print cartridges might also produce incorrect colors.
•Toolbox (Windows):  Open the Toolbox. For more information, see 
Toolbox
(Windows). Click the Printer Services  tab, and then click Calibrate Color  and
follow the onscreen instructions.
• HP Printer Utility (Mac OS):  Open the HP Printer Utility. For more information,
see 
HP Printer Utility (Mac OS) . Click  Calibrate Color  and follow the onscreen
instructions.
Maintain the device
The device does not require scheduled maintenance, except for replacing the ink
service module. For more information, see 
Replace the ink service module . You

Clean the device
When you clean the device, follow these guidelines:
• Clean the outside of the device with  a soft cloth moistened with mild detergent and
water.
NOTE: Clean the device only with water or water mixed with a mild detergent.
Using other cleaners or alcohol can damage the device.
• Clean the inside of the front access cover with a dry, lint-free cloth.
CAUTION: Be careful not to touch the rollers.  Skin oils on the rollers can
cause print quality problems.
Clean the print cartridges
If printed characters are incomplete, or if dots or lines are missing from the printouts,
you might need to clean the print cartridges. These are symptoms of clogged ink
nozzles, which can result from prolonged exposure to air.
NOTE: Before you clean the print cartridges, make sure the print cartridge ink
levels are not low or empty. Low ink levels can also cause incomplete characters,
missing lines, or dots on the printouts. Check the print cartridge lights to make sure
they are not on. For more information, see 
Control-panel lights reference . You can
also check the status of the print cartridges from the Printer Status tab in the
Toolbox (Windows), HP Printer Utility (Mac OS), or Toolbox software for PDAs.
Replace any low or empty print  cartridges. For more information, see 
Replace the
print cartridges.

Store print cartridges
The print cartridge protector is designed to keep a print cartridge secure and prevent it
from drying out when it is not being  used. Whenever you remove a print cartridge from
the device with the intention of using it again later, store it in the print cartridge
protector. For example, store the black print  cartridge in a print cartridge protector if
you are removing it so you can print  high-quality photos with the photo and tri-color
print cartridges.
NOTE: If you do not have a print cartridge  protector, you can order one from HP
Support. For more information, see 
Support and warranty . You can also use an air-
tight container, such as a plastic tub. Make sure the nozzles are not touching
anything when you store the print cartridges.
To insert a print cartridge into the print cartridge protector
▲ Place the print cartridge into the print  cartridge protector at a slight angle and snap
it securely into place.

							To remove the print cartridge from the print cartridge protector
▲Press down on the top of the print cartridge protector to release the print cartridge,
then gently remove the print cartridge out of the print cartridge protector.
Replace the ink service module
The replaceable ink service module holds waste ink from the black print cartridge.
When it is almost full, the device lights will prompt you to replace it. For more
information, see 
Control-panel lights reference .
When the ink service module is full, the device will stop printing. If you have a new ink
service module, install it immediately by following the instructions that come with it.
Otherwise, visit 
www.hp.com/support  or see Support and warranty to get a
replacement. In the meantime, remove the black print cartridge to continue printing.
The device can print using only the tri-color print cartridge but the color results and
print speed will be affected. For more information, see 
Print with a single print cartridge .
CAUTION: Allowing the ink service module to fill completely can result in black
ink spillage. Take care to avoid spilling the ink in the ink service module. Ink can
permanently stain fabric and other materials.
NOTE: If you have installed the Toolbox (Windows), you can choose to display
error messages on your screen when there is a problem with your device. For
more information, see 
To share the device on a locally shared network .
